In a Friday interview on Boston's WTKK-FM radio, the incumbent said he is giving up booze until November's Election Night. Brown noted that he has not had any type of alcohol since January 1, referring to the adjustment as "one of those New Year's things" that he did "on a stupid bet."

Brown's battle with Democratic challenger Elizabeth Warren had its highlights this week, with taxes at the forefront of the conversation. The Boston Globe requested on tax day that both candidates release six years' worth of returns.

Warren's campaign was open to two years of releases, under the stipulation that Brown unveil his own documents from that same period. Brown's campaign did not commit to anything, but added that it may comply with the six-year timeframe.

By Friday, Boston's Fenway Park was serving as a live backdrop for the senate race. To celebrate the landmark ballpark's 100th anniversary, Warren and Brown appeared on Friday's edition of MSNBC's "Morning Joe," trading shots on issues like financial reform.

"I think this is about whose side you stand on," Warren said. "You know, you just kind of look at where the two parties are. Scott Brown got an award from Forbes magazine for being one of Wall Street's favorite senators."

Brown noted he voted with Democrats on the financial reform bill, and aligned that fact with his efforts to serve as a bipartisan official.

"The only reason that we’re getting things done is because I’m there and we’re working hard across the aisle finding people of goodwill to solve problems," he said.
